Observability canonical (phase-variable) form for non-linear time-variable systems. International journal of systems science, 15(9), 949-958.M. Zeitz: Observability canonical (phase-variable) form for non-linear
Voltage controlled oscillators contain a variable tuning element, such as a varactor diode, which varies its capacitance with input voltage, allowing a tuneable resonant circuit, which permits a range of frequencies to be generated (Figure 9). The PLL can be thought of as a control system for ...
SIRIUS soft starter For preventing mechanical impacts in machines and current peaks in the power system – particularly for large motors. SINAMICS frequency converter Variable speeds with standard-performance and industry-specific frequency converters....
Shimada and co-workers,32 who studied the same PVDF/PMMA system using the ESR technique, found a UCST (Figure 6). The actual concentrations of PMMA in mixed phases, such as the PMMA-rich and PMMA-poor regions, can be determined by the ESR technique.35 In the 11/89 composition, the ...
In general, most inverter designs are transformerless or non-isolated. String inverters typically rely on two-stage power conversion. First, the DC-DC stage converts variable DC voltage into a suitable or fixed voltage required by the DC-AC inverter stage. At the same time, it ensures maximu...
The Greatwall/Ensa/PP2A-B55 pathway is essential for controlling mitotic substrate phosphorylation and mitotic entry. Here, we investigate the effect of the knockdown of the Gwl substrate, Ensa, in human cells. Unexpectedly, Ensa knockdown promotes a dra
It is seen that the effect of the imaging system is equivalent to convolving the WDF of imaging PSF over the spatial variable x. More importantly, Wpsf(x, u) is zero when u falls outside of the pupil (in most cases the pupil function is equal to a circ-function, i.e., P(u)=...
The transportation of essential items, such as food and vaccines, often requires adaptive multi-temperature control to maintain high safety and efficiency. While existing methods utilizing phase change materials have shown promise, challenges related to
As can be seen from Equation (16), the phase sensitivity of the interferometer depends on the noise of the measured variable and its rate of change for the phase of the interferometer. Commonly, the measured variable can be the photonic number, orthogonal component, parity operator, and ...
